I had a chance to call the dealer this morning. Turns out, they are sold as individual units which is good. The bad...I was quoted a price of $9.50 per unit - that works out to over $30 per face foot! Are you guys paying that much???

I don't think so. I found it in last years catalog and it didn't say it was new then. But to be honest with you, I am very unfamiliar with the Unilock line. I received some literature from a dealer that started carrying it last season, so I have yet to try any of the product.
